ONA Block is a semi-solid odor neutralizing agent that slowly releases to eliminate any airborne smells. Made from a complex formula, it uses essential oil technology to destroy a wide spectrum of organic and non-organic odors. Not a masking agent; it neutralizes odor. Size: 6 oz. container (3″ x 3″ – fits almost anywhere).
Directions: Remove the ONA Block from the container and place in areas where odors lurk. Works up to 30 days depending on airflow and ambient temperatures. To reduce the strength of the block, poke holes in the cover and replace on the container. This will also prolong the life.
PRO (shown) – Has virtually NO fragrance but is very powerful. It has a light scent in its container but leaves the air merely smelling fresh — like after a summer rain.
